drm/i915/dpt: Make DPT object unshrinkable

2024-06-21T12:40:36+00:00

commit 43e2b37e2ab660c3565d4cff27922bc70e79c3f1 upstream. In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm->bound_list. Then it tries to rewrite the PTEs via a stale CPU mapping. This causes panic.

drm/i915: fix applying placement flag

2024-03-04T10:09:32+00:00

Switching from a separate list to flags introduced a bug here. We were accidentially ORing the flag before initailizing the placement and not after. So this code didn't do nothing except producing a warning.

drm/i915: Bypass LMEMBAR/GTTMMADR for MTL stolen memory access

2024-02-06T23:58:54+00:00

On MTL accessing stolen memory via the BARs is somehow borked, and it can hang the machine. As a workaround let's bypass the BARs and just go straight to DSMBASE/GSMBASE instead. Note that on every other platform this itself would hang the machine, but on MTL the system firmware is expected to relax the access permission guarding stolen memory to enable this workaround, and thus direct CPU accesses should be fine. The raw stolen memory areas won't be passed to VMs so we'll need to risk using the BAR there for the initial setup. Once command submission is up we should switch to MI_UPDATE_GTT which at least shouldn't hang the whole machine. v2: Don't use direct GSM/DSM access on guests Add w/a number v3: Check register 0x138914 to see if pcode did its job Add some debug prints Cc: Joonas Lahtinen Reviewed-by: Andrzej Hajda Reviewed-by: Radhakrishna Sripada Reviewed-by: Nirmoy Das Tested-by: Paz Zcharya Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20240202224340.30647-5-ville.syrjala@linux.intel.com
